I have three APC units that are 20 years old now and two that are five years old. I keep gear as long as I can. I have units in my rig nearly sixty years old. That is the key to having a really nice system, not having to chuck money at replacements. In fact the preamp and turntable I am...

...your gear instantly from AC and go to battery when power is out of the set voltage requirements and will even shave voltage if it get too high and will let you know if the AC line is out of spec. so I would not worry about that. I have always used nits from APC and found them very satisfactory.

Amazon price is $38.99

All my APC units do that. He needs to order smart UPS units from APC. They can and do, shave high voltage and boost low. That is an essential part of the engineering and specification of a high end installation.

Skipping whole house surge protection is a bad move. Weather is getting more severe, and all your appliances are stuffed with ICs. A lightening surge can cost you thousands outside of AV. Your home has literally thousands of ICs in it now. Whole house protection is code where I live and...

That is a definite not necessarily.

...These monitor the power and switch to battery in the event of power interruptions and and voltage abnormalities. I use UPS units from APC. This has been a long winded way, of saying, good surge protection is job one. If you want more then you need a UPS and not so called power conditioners.

What are you connecting to that APC H15? Those H15 units are only 1.5KVA and KVA are not watts. 1.5 KVA is 1000 watts. Power protection is only required for the fragile equipment. It is particularly not recommended that power amps be connected to them. The turn on current is too high for...

Did you just plug in the h15, or was any gear plugged into it. If there was nothing connected to your h15, then I'm suspicious of your house electrical system, like a live neutral swap for instance. This is just NOT typical for APC gear, and I suspect you have a problem somewhere.

...were much more common, but the UPS units did their jobs. If you have a costly system with significant monetary investment the UPS units are essential basics in my view. I use APC units, three in the AV room and one in each of the other systems. It also protects the Internet infrastructure.

We have been over this many times. The answer is whole house surge protection at the entry point of electric service. This is by far the most important. Then you can consider a UPS unit. I protect my gear with units from APC.

The Panny plasma in our great room was purchased in 2008, the one in our family room in 2010. So 15 and 13 years old. They have been powered via APC UPS units. Also whole house surge protection.

...entry point and the optimal location for the whole house surge protection. You do need a UPS with gear that expensive. I have used units from APC and had good results. I have used their units for 17 years now. I have five of their units installed here. There are three for the AV room...

I was hesitant to recommend used, as this is critical equipment, but he won't be in budget with new gear. I would recommend he up his budget.

Most likely the voltage regulator has failed. Time for a new unit. APC recommended.

I use standard computer APC UPS units of the correct power. Remember VA is not watts for an AC circuit, only a DC circuit. Do not connect power amps to UPS units. For the phase angle of a home AC circuit 300 watts is 500 VA. So your UPS will be specked in VA, but your processor will be...

I do. Power conditioners, will not prevent on and off surging in brief power cuts. I have an extra incentive, as gear stays powered for the five seconds it takes my generator to start. Pros, use UPS units in electronic infra structure. I have said this many times, whole house surge...

APC are still a going concern, and make excellent gear. I have five of their units currently in use. To do a decent job really requires batteries in the unit. A unit without batteries is of little use. What you need is a UPS of the correct power. I can thoroughly recommend APC...

If it was connected to analog turntable, then yes it would. This will not be a problem in he mains supply. You need to focus on the digital unit that is causing the problem. So focus on the units that actually exhibit this symptom. This is very unlikely to be external, but more likely an...

Shielded speaker cables are a bad idea and a poor design. The reason is that it increases cable capacitance. Speaker cables can be a source of interference, as it can transmit to the high gain stages via negative feedback. IF this occurs the solution is to run the speaker cables in grounded...
